This did reveal the error: Permission Denied. I checked the directory and "everyone" has "full control" in it. I am thinking that maybe the module is trying to delete the temp file while it still has an open handle on it. I don't even know where that handle is. The module API provides a funky reference to the handle that seems to be some sort of alias. Can anyone think of any other reason that permission would be an issue? Does anyone know how to close the handle?
